As I can see from the questions being asked that a large number of you guys have done lab #7. So please help me out by answering how to do question number 4 and 7. I do know the formula for yield but if we use the exact composition from part 2, do we not we get 100% or I am making a mistake here.

Anyone's help will be appreciated.

As far as I know, I do not think you should get a 100% yield. If you did get a 100% yield, this would mean that all of the crystals which you created were obtained and accounted for in the final massing. This is highly unlikely, since we transfered the crystals into several containers repeatedly, causing us to loose some of them.
